Kaplan–Meier plots indicated that HCC patients from the TCGA‐LIHC dataset with high CDKN2B‐AS1 expression (CDKN2B‐AS1high) had shorter OS (Figure 3A), progression‐free survival (Figure 3B) and disease‐specific survival times (Figure 3C) compared to those with low CDKN2B‐AS1 expression (CDKN2B‐AS1low). The gene discussed is CDKN2B; the disease is hepatocellular carcinoma.
